Some in Colorado are facing scrutiny for providing rides and t-shirts to people who can show they voted.

The owners of a hip-hop clothing line that sponsored limousine rides, T-shirt give-aways and drink specials to voters who proved they cast a ballot during early voting Thursday in Denver and Boulder could face criminal charges for the promotional event.

Rich Coolidge, spokesman for the Colorado Secretary of State’s Office, said state election laws prohibit anyone from essentially bribing someone to vote.
